Letters Patent No. 82,689, dated October- 6, 1868.

IMPROVED TRUSS.

TO ALL WHOM IT MAY CONCERN:

Be it known that l, JOH BURNHAM., loi' Batavia, in the county of Kane,and State of Illinois, have invented a new and improved Truss; and Idohereby declare that the following is a. full, clear, and exactdescription lthereof, which will enable those skilled: in the art ,tomake and use the same, reference being had to the accompanyingidrawings,forming part ot' 'this specification.

Thisinvntion relates to a new and useful improvement in trusses, and itconsists in attaching the padlevcr to the band by-means of-aball-and-socket joint, substantially as hereinafter fully shown anddescribed, whereby the pad'may be adjusted in any desired position topress properly on the rupture, and to suit either a. iat or prominentabdomen, and also to convert the'truss into a right or left one; that isto say, so that it may be adjusted to the right or left side of thebody, as may be required. a

i The accompanying drawing represents a perspective view of my nvention.

A is the strap of the truss, in which the steel or metal band is fitted,as us'ual, and B is a socket at the end of the band, composed of twoparts, a b, connected together by screws, c, and having a concave, whichis a portion of' a hollow sphere, to receive a balk-d, the parts a bbeing made to press against the ball, in a greater' or less degree, bymeans of the screws c.

Thev ball d has an arm, e, projecting from it, and from this -arm e thepad-lever C projects, at right angles, the pad D being attached to theouter end of the lever C, as usual, or in any proper way.

By thus connecting the pad-lever C to the spring, by means of a.ball-and-socket joint, the pad may he adjusted in any desired position,so as to press properly upon the rupture,'and when properly adjusted,may be secured firmly in position by screwing the two parts, a b, ofthesocket together, so that the ball d will be tightly grasped; and thetruss may be applied to either: side of the body, asithe pad-lever C maybe swung entirely around, and the pad adjusted to either side oi' tbelever. A

I do not confine myself to the precise construction of a holland-socketjoint, as herein shown and described, for that may be varied or modifiedin ,different ways, andthe same end attained.

I claim as new, anddesire to secure by Letters Patent- 'lhc attaching ofthe pad-lever of the truss to the spring, in the band or strap thereof,by means of a.

ball-and-socket joint, substantially as shown and described.

JOHN BURNHAM.
